Project Description

Hadoop_Inspector

To review our complete set of documentation please see our wiki page

Background

Data quality problems have plagued analytical systems for twenty years: continually appearing in the top four reasons for project failure.

In this space data quality problems loom large - a small defect that could be safely ignored or forgotten in the transactional world hamper queries and cause users to question our credibility for months.

The advent and innovation in Big Data and Data Science has not diminished this challenge. On Hadoop specifically: * Data generally lacks any enforced constraints to ensure data validity * Data is being added faster than ever, with less time to research upstream and ETL pipeline issues * We are building vast systems, sometimes with hundreds of thousands of tasks being defined * We often have democratized access to our clusters - with dozens of different people adding data.

Additionally, in these large clusters most teams struggle to comply with policies and other requirements, whether regulatory, corporate or defined by their own teams. These might define general data retention requirements, or specific requirements for individual tables. They might define table naming conventions, security requirements, or stats aging & collection requirements.

Objective

Hadoop-Inspector was built to address the needs to manage data quality within large, complex, and constantly loaded clusters that were unfulfilled by simple QA testing during development. It offers a solution more like an automobile assembly line: continuous quality control (QC) that can account for changes to upstream systems, accidental changes to production, data migration errors, and ETL/Ingest defects.

Current Status

The software consists primarily of three parts:

  • hadoopinspector-runner.py - a test-runner that writes results to a SQLite database and can produce a report of test results. This is the primary and most updated component at this time.
  • hapinsp_httpserver.py - serves the UI.
  • hadoopinspector-demogen.py - which can generate 50,000+ check results against a hypothetical user hadoop environment. This is used to exercise the UI.
